What folder is the media in? I ask because some folders that our clients (Snagit, Camtasia, Jing) create and upload to by default do not show the breadcrumb while our default Screencast folder template does.

If you are a Screencast Pro subscriber you can customize the template for a given folder, and one option in a custom template is to show the breadcrumb. If you are not Pro, but would still like to show the breadcrumbs you can create a new folder and then change Snagit or Camtasia to upload to that new folder instead. This may change the look of your view page, however, so keep that in mind.
